      Q:Does this need wind or is it heat that makes it turn?
      by|May 6, 2023
      1 Answer
      Answer This Question

      A:  The turbine uses the wind to help pull excessive attic heat and moisture from the attic and acts as a static vent when no wind is present.

            The 12" turbine vent I bought was a perfect replacement & fit. My other turbine vent lasted 30 years, hopefully this will last as long.

            Good product and fit exactly. Very quiet in operation and I don't miss the grinding noise of my old units! Shipping was convenient and arrived as expected. One of my 3 units was damaged in shipping but I contacted Home Depot and a replacement was immediately shipped. Returned the damaged unit to my local store for credit and process was very painless. I would recommend this product from a cost and quality standpoint and kudos to Home Depot for the great customer service from start to finish.

            Best Product 2016- Normal replacement heads are of the old design- no support to the top bearing and make you but another flange which either ends up at the dump or at Habitat for resale just because it's included. The flange should last decades and is not a standard replacement item. This is just a superior designed replacement head without a flange to waste- just what the house doctor ordered and no more (no waste). Why is it superior? Side loads from wind gusts stress and wear out the bearing assembly eventually breaking the vertical shaft that the turbine rotates on. Then the wobble and eventual jam occurs making them annoyingly noisy through the dying period. This design supports the top bearing externally with three 'spider' legs transferring the side load down to the base collar which is screwed into your existing flange. Any wind gust side loads are transferred to the stable base which should extend the life of both the top and bottom bearings, protecting the vertical drive shaft from cracking. Fit to Flange- I have two flanges of one style and the third was a different design (more sheet metal custom made). All three replacement heads went on easily with very little play on the 12" diameter. After screwing each unit to both types of flanges a tug on the spider legs verified that the fit was great which should prevent wobble. Totally impressed with the replacements meeting the 12" existing diameters. Installed (25) days ago within 1 hour of picking them up. Total installation and cleanup time (carrying old ones down) around (40) minutes for (3) replacements. Used a battery powered drill and a standard drill bit to drill the holes for the new screw locations, and one screwdriver. After (25) days still totally whisper quiet and stable. On first view, I thought the spider legs would look weird but I keep one leg facing the front of the house on all three and the shaping virtually disappears. If anything, it adds a little Star Wars spaceship detailing and I now have the coolest Turbines in the neighborhood. Kudos to Home Depot for finding and carrying this product. On the morning that I was ready to go to Home Depot to pick up the old style we did one more search on the site and these popped up. Ordered them online and waited another (5) days to get a superior product. Thank you, Home Depot,

            Sturdy Product, good price
            I replaced an old worn out internally braced turbine with this one. Fit right on the existing 12" base perfectly. The holes even lined up with the old base. This turbine seems a lot stronger than the old one which we need because we get allot of high winds.

            I put it off two long and payed the price of a high electric bill!
            With all the 90+ degree days in July( in GA.) and after getting $300+ electric bill it was time to replace the three non working roof turbine on our home. After checking for the correct size and for the best price I finally found them on line at Home Depot. They were so easy to install, it only took less than thirty minutes for me to replace all three and I am 74 years old. They are making a difference because I check daily on line with my GA. Power account. The pay back may take a while but the satisfaction was immediate! Great price and fast shipping.

            Works great and much easier than changing the whole vent tearing into the roof.
